Semi submersible drilling rig design

Semi submersible drilling rig design

Mobile offshore drilling units (MODU) Semi-submersible rigs make stable platforms for drilling for offshore oil and gas. They can be towed into position by a tugboat and anchored, or moved by and kept in position by their own azimuth thrusters with dynamic positioning. The International Maritime Organization. . A semi-submersible platform is a specialised used in offshore roles including as rigs, safety vessels, oil production platforms, and heavy lift cranes. They have good . The semi-submersible design was first developed for activities in the early 1960s. Bruce Collipp of is regarded as the inventor.However, . • – Consultants designers• – Consultants designers• – Info on Boskalis transport ships• – Photos of Mighty Servant 2 hauling USS Samuel B.
