The '''GSL class of jetty berthing pontoons''' are a series of four non self-propelled yardcraft built by [[Goa Shipyard Limited]] for the [[Indian Navy]].

The [[pontoon (boat)|pontoon]]s are [[catamaran]]s with rectangular shaped twin flat-bottomed hulls. The twin hulls are connected by [[truss]]es of round pipes with a steel deck covering the transverse beams. Each hull is divided into eight watertight compartments. The pontoons have hydro-pneumatic fenders on both sides to facilitate high energy absorption and low reaction loads. Two vertical roller fenders are located at the forward and aft corners, on the side, for corner protection. They are intended for berthing vessels having displacement up to 40,000 tons on a [[jetty]] by serving as spacers between the jetty and the ship.<ref>{{Cite web |url=http://www.irfc-nausena.nic.in/rfp/Tender_Pontoons_Gangways_dgnp(m).pdf |title=Tender Pontoons Gangways |access-date=26 February 2013 |archive-date=10 June 2015 |archive-url=https://web.archive.org/web/20150610221727/http://www.irfc-nausena.nic.in/rfp/Tender_Pontoons_Gangways_dgnp(m).pdf |url-status=dead }}</ref>

They were built as part of an order to also construct one [[GSL-class service barge pontoon|Service Barge Pontoon]] and four [[gangway (nautical)|gangway]]s. The [[request for proposal]] was issued on 7 March 2011 and the contract was signed in June 2011. By February 2013 all four pontoons had been delivered. Two pontoons were stationed at Naval Dockyard, [[Mumbai]] and two at the Naval Base in [[Karwar]].<ref>{{cite web|url=http://www.goashipyard.co.in/NewsEventsDetails.aspx?id={0054-0108-0148-0128-0161-0192-0225-0256} |title=News & Events Details |publisher=Goa Shipyard |date= |accessdate=2013-05-07}}</ref>
