Japanese maritime transport company Mitsui O.S.K. Lines, Ltd. (MOL) will upgrade its from Inmarsat Maritime’s Fleet Xpress service to NexusWave, the companies announced May 21. 

Local Inmarsat partner JSAT Mobile Communications will be responsible for implementing and supporting the upgrades on board, covering a fleet that includes liquefied natural gas (LNG) carriers, oil tankers, and car carriers.

“Our digitalized and connected ships are becoming floating operations centers and homes for our crew, and Inmarsat’s NexusWave will help keep them connected to high-speed internet and support our onboard digitalization strategy,” commented Junichi Yoshiyama, chief digital & information officer of MOL. 

Inmarsat Maritime introduced NexusWave last year as a managed service that integrates its existing Global Xpress (GX) Ka-band network with Low-Earth Orbit (LEO) services, coastal LTE services, and an additional layer of satellite L-band. It combines multiple network underlays in one fully managed, bonded solution

Inmarsat Maritime is a Viasat company. In Viasat’s recent investor call, the company reported that Maritime revenue was down 8% year-over-year in the fourth quarter, but the company ended March 2025 with more than 100 ships in active service for NexusWave and orders for nearly 500 more. Viasat plans to increase the rate of installations in the first quarter of fiscal year 2026.
