Other Support Activities for Water Transportation

The NAICS code 488390, "Other Support Activities for Water Transportation," encompasses a diverse range of maritime and marine-related support services that do not directly involve vessel transportation. These services include marine cargo checking, ship surveying, floating dry dock operations, vessel maintenance and repair, maritime logistics support, and specialized marine inspection and certification activities. The category covers auxiliary services that are critical to the smooth operation of water transportation infrastructure and maritime activities across various sectors.

Federal Contract Awards under this NAICS code demonstrate a wide variety of maritime support services, with most contracts ranging from $2,000 to $12 million and typically lasting between 6-36 months. Frequent contractors include Asahi Tanker Co. (maritime logistics), Seaward Marine Services (vessel maintenance), and Intertek Testing Services (marine cargo surveys). Predominant funding agencies are the Department of Defense (Navy, Military Sealift Command), Department of Agriculture, and Coast Guard. Most awards are unrestricted, with few set-asides, and frequently involve international locations like Japan, various African countries, and U.S. coastal regions. Common service types include bunkering, vessel maintenance, maritime inspections, logistics support, and specialized marine transportation services.

Recent Federal Contract Opportunities highlight diverse maritime support requirements across multiple agencies.

Performance locations span domestic coastal regions and international maritime environments. Opportunities consistently emphasize technical capabilities, safety standards, and specialized maritime expertise. Most solicitations are unrestricted and target firms with specific maritime operational capabilities, marine certifications, and proven track records in supporting complex maritime missions.
