There are a range of 'A' frame LARS designed specifically to match your Seaeye ROV, that are equally suitable for launching other manufacturers' vehicles.
The 'A' frame can be erected using the system's own rams without the need of any other external lifting devices. This simplifies and reduces the cost of mobilisation and commissioning to a new location.
The pivot point for the 'A' frame is 2 metres above the deck which allows the ROV and TMS package to clear vessel guard rails up to this height and to achieve a greater overboard reach than a conventional 'A' frame pivoted at deck level.
The forward position of the 'A' Frame rams keeps side access to the ROV and TMS clear of obstructions for essential maintenance and pre-dive checks.
Seaeye offer four standard LARS types whose Type number is designated by the umbilical winch capacity and system safe working load. For example, for Type 1K1-1.25, 1K1 refers to a winch capacity of 1100 metres and -1.25 to a 1.25 tonne SWL at 3G which is widely regarded as suitable for operations in sea state 6.
Each of these systems can be provided for safe area or zone 2 operations and an optional latch mechanism can be fitted to the sheave to capture a vehicle or TMS bullet for safer launch and recovery.
In the stowed/ transport position the LARS is extremely compact and small enough to be shipped in a standard ISO container if this were required. A crash frame is fitted around the winch and HPU with additional protection during transport provided by the 'A' Frame in its stowed position
