Jubilee Field Development Phase-1
Project no: 930
Project name: Jubilee Field Development Phase-1
Project description: Tekmar Subsea
Project completion date: October 2009
Description of product
26-off 24" NS suction pile plugs
52-off suction pile receptacles
ROV torque tool multipliers
These products were installed onto our clients suction piles topside and are capable of ROV removal and re-installation subsea.
The 24" NS plugs were designed to seal a differential pressure 7.5 bar.g. All products were individually pressure tested, witnessed by a client representative and supplied with a full fabrication certification package.
The plugs were designed to have a maximum submerged weight of 60 kg. To achieve this Tekmar manufactured in-house subsea buoyancy systems capable of operation up to depths of 1,500 msw. The buoyancy modules were mounted integrally within the buoyancy plug.
Our client also specified a maximum torque setting of only 150 Nm. This would enable activation by the ROV manipulator and reduce installation time. Tekmar designed and supplied a sub sea torque multiplier that increases the initial activation torque up to a setting that were the the desired seal was achieved.
The plug was fitted with ROV intervention features and also a class 3 torque tool receptacle which would allow the sealing pressure to be increased if required.
