The platform always has at least one logistics support vessel in attendance, which shuttle supplies and provides on-station emergency support. These support vessels are also tasked during the spring and summer months to tow small and medium-sized icebergs which might collide with the platform, even though the GBS is engineered to withstand such a hit. The crew consists of 280 people who spend 3 weeks on the platform and three weeks on land, flown to and from the platform by helicopter.
