This is an appeal from an order granting a motion to quash the service of summons and complaint upon respondent and defendant, Anders-Jahre and Company.

A résumé of the facts is as follows:

In the latter part of 1957 appellant was engaged in the removal of the concrete piers of a certain bridge which was located across the entrance to the west basin of Los Angeles Harbor. On September 11 of that year, the vessel “Janus,” owned by respondent, attempted to enter the west basin while tied to and assisted by the tug “Long Beach.” The “Long Beach” was owned and operated by defendant, Wilmington Transportation Company. At all times during the event in question, a compulsory pilot in the employment of defendant, City op Los Angeles, was on the bridge of the “Janus” performing his duties. While both vessels were in the process of entering the west basin the tug “Long Beach” struck one of the concrete piers of the bridge and caused the pier to topple and fall beneath the surface of the water. Appellant filed an action claiming damages resulting from the negligence and trespass on the part of defendants. The summons and complaint were served upon respondent Anders-Jahre and Company, by personal delivery to an officer of W. H. Wickersham and Company, Inc., a company which acted as agent for the owners of the “Janus” during the time the ship was in Los Angeles Harbor. A motion to quash was filed on behalf of respondent on the grounds that at the time of such delivery respondent was not doing business in the State of California and that W. H. Wickersham and Company, Inc., was not, at the time of service, an agent, officer or manager of respondent and was not authorized to receive service of the summons and complaint. The motion was granted upon the latter ground.

Subsequently, appellant obtained an order from a superior court commissioner providing that service be made upon respondent by personal delivery of the summons and complaint to the Secretary of State. Service was effected in that fashion. A second motion to quash was filed and served on behalf of respondent on the grounds that respondent was not doing business in the State of California at the time of such service and that the service of process was improper and of no legal effect. This motion was based upon a memorandum of points and upon the affidavits of one Frithjof Bettum, a member of the board of directors of respondent and one Boy Blydenburgh, Secretary and General Manager of W. H. Wickersham and Company, Inc. Additional memoranda of points and authorities were filed by respondent and by appellant and reference was made by appellant to respondent’s answers to appellant’s interrogatories which had previously been filed in the action.

The facts relied upon by appellant to show that respondent was amenable to process in the State of California at the time service was effected are contained in the affidavits and in the answers to interrogatories referred to above. An examination of those affidavits and answers to interrogatories discloses among other things the following:

That respondent, Anders-Jahre and Company is a corporation existing under the laws of the Kingdom of Norway with its principal place of business in Sandef jord, Norway.

Respondent’s business consists of the ownership and operation of steamships in domestic and foreign trade, including the “Janus.” Four vessels owned by respondent, other than the “Janus,” called at California ports from March 12, 1951, up to and including the date of the accident in question as well as some calls which were made subsequent to said accident. Over 20 calls were made by those vessels to California ports. Substantial quantities of cargo were discharged in California from the various vessels owned by respondent.

Interrogatories were propounded by the appellant to Anders-Jahre and Company, the first of which was: “With respect to each of the visits of the vessels referred to in Paragraph 7 of the affidavit of Frithjof Bettum filed with the defendant’s Motion to Quash Service of Summons, please state: the amounts of cargo discharged at Los Angeles or San Francisco on each of the occasions referred to in said Paragraph 7 by each of the vessels referred to in Paragraph 7.” The “Answers to Interrogatories” set forth the following:

At all times while respondent’s vessels were in California the crew members were in the employment and pay of respondent. Also, respondent hired, supervised and directed the master and crew of each vessel. Large quantities of fuel oil were purchased when respondent’s vessels called at California ports. The crews of the various vessels were paid and permitted to go ashore in California by respondent. Respondent issued bills of lading covering various cargoes scheduled to be unloaded at California ports.

Various California companies were employed as agents to act on behalf of respondent’s vessels. These companies included Kerr Steamship Company, Inc.; General Steamship Corporation; Williams; Diamond and Company; and W. H. Wiekersham and Company, Inc. The latter was retained to act as agent in assisting the “JanUs” on the occasion of its call at Los Angeles Harbor in September of 1957.

According to his affidavit, Roy Blydenburgh is the secretary and general manager of W. H. Wiekersham and Company, Inc., a corporation which acts as port agent in Los Angeles on behalf of several foreign and domestic shipowners. The duties of a port agent include arranging for the replenishing of provisions, water and fuel, the procurement of supplies and parts, the payment of docking, pilotage and stevedoring fees and other like tasks.

It appears from the record that some additional tasks were performed for respondent by W. H. Wiekersham and Company, Inc., in overseeing or in some way assisting the completion of temporary repairs which were made on the “Janus” in Los Angeles.

The trial court did not specify the ground for its order granting respondent’s motion to quash. It is an established rule that :

It is also true that when the evidence is not conflicting, the reviewing court is not bound by the findings based thereon. (Cosper v. Smith & Wesson Arms Co., 53 Cal.2d 77, 81 [ 346 P.2d 409 ].) There is no dispute as to what activities actually occurred in California. The pivotal question is as to the legal consequences that necessarily flow from these activities.

In Jeter v. Austin Trailer Equipment Co., 122 Cal. App.2d 376 [ 265 P.2d 130 ], the issue before the court was whether a foreign corporation was amenable to services of process by serving the Secretary of State under the provisions of section 6501 of the Corporations Code. In deciding the question, the court pointed out at page 381 that:

The pertinent provision of section 411 of the Code of Civil Procedure provides:

Corporations Code, section 6501, provides in part:

The pertinent provision of section 6504 of the Corporations Code provides:

Section 6203 of the Corporations Code provides:

The court in Carl F. W. Borgward, G.M.B.H. v. Superior Court, 51 Cal.2d 72 [ 330 P.2d 789 ] at page 76 stated:

Therefore, if a foreign corporation is “doing business in this State,” no inquiry need be made as to whether the business is of an inter or intrastate nature.

Although the service of process in Cosper v. Smith & Wesson Arms Co., 53 Cal.2d 77 [ 346 P.2d 409 ], was pursuant to section 6500 of the Corporations Code (i.e., service on agent), the rationale is equally applicable to service pursuant to section 6501 of the Corporations Code. The court stated on page 82:

“The validity of the service of process pursuant to section (6500) of the Corporations Code depends first on whether the foreign corporation is ‘doing business in this State’ within the meaning of the statute. (Code Civ. Proe., § 411, subd. 2.)

As this court said in Henry R. John & Son v. Superior Court, 49 Cal.2d 855 , at page 858 [ 323 P.2d 437 ] :

The record negates any contention that respondent had engaged in but sporadic transactions within the state. Respondent’s vessels have called at California ports from March 12, 1951, up to and including the date of the accident in question as well as calls which were made subsequent to said accident some 20 times. What constitutes a regular course of business dealings will, of course, vary with the type of business involved. Certainly the activities of respondent are more significant than the minimal contacts deemed sufficient in McGee v. International Life Insurance Co., 355 U.S. 220 [ 78 S.Ct. 199 , 2 L.Ed.2d 223 ], where the foreign corporation elected to deal with the insured only by mail. In James E. Murphy v. Arrow Steamship Co., Inc., 1954 A.M.C. 1423 (E.D.Pa. 1954), defendant foreign corporation was held to be “doing business” although only seven calls of the foreign corporation’s vessels had been made in a period of four years.

Whether a state may constitutionally assume jurisdiction involves a balancing of many factors.

It was said in Fisher Governor Co. v. Superior Court of the City & County of San Francisco, 53 Cal.2d 222, 225 [ 1 Cal.Rptr. 1 , 347 P.2d 1 ] (decided December 8, 1959), as follows:

If we apply the aforementioned factors to the present case the record discloses that the plaintiff (Emsco), and the defendants, city of Los Angeles and Wilmington Transportation Company are California residents; only respondent is a nonresident. The physical evidence with reference to the accident is located in California; to prosecute the action other than in California might well require a trip to Norway; if respondent were not subject to the jurisdiction of the California courts, any determination of the issues would not be res judicata upon it, and there is a probability of conflicting adjudications; there would of course be multiplicity of suits if plaintiff was required to bring a second action against respondent; the cause of action arose out of re spondent’s local activities (i.e., entering Los Angeles Harbor).

Since respondent is doing business in California, there is no issue as to whether section 6504 of the Corporations Code is applicable.

We believe that it ivas error for the court to grant the motion to quash the service of summons and complaint.

The order is reversed.

Wood, P. J., and Lillie, J., concurred.
