Aker Subsea recently introduced a new internal subsea tree cap that promises ease of installation at depths of 10,000 ft below the ocean surface. The cap, which can be installed and retrieved by a remotely operated vehicle (ROV), also promises more efficient installations at lower overall costs. The Aker Subsea tree caps are designed for use on concentric bore, vertical subsea trees. The cap acts as a barrier to keep the subsea environment clean in the event of any leaks above the annulus and production swab valves.
