Role in marine infrastructure

Masirah Marine is the trading name of Masirah International Technical and Marine Services LLC, an Oman-based contractor operating since 2000. Its official portfolio covers buoy and SPM installation and maintenance, subsea anchoring and chain work, marine pipelines, commercial diving, hydrographic and geophysical survey, dredging, piling and harbour construction. The portfolio provides an exact historic contract link at Liwa Fishery Harbour: quay-wall block installation in 2017 with Galfar named as client. The company publishes crane and spud barges, landing craft, three twin-screw tugs, a diving boat and a hydrographic survey vessel, but no ASD tug or anchor-handling vessel. Direct market intelligence identifies Masirah as the most likely selected installer for ACME's Duqm green-ammonia CBM; its portfolio still does not name ACME, Bluewater or that package, so the Duqm role remains Reported rather than Confirmed.
