From: Just in time vessel arrival system for dry bulk carriers
 | Vessel/voyage characteristics | External effects |
---|---|---|
General conditions/assumptions | Equal dimensions and technical details | (Nautical) Speed advancement and -delay effects are deemed not to apply for any route (total value of wind-, sea-, swell and current effects are deemed to be equal to zero, SOG equal STW, DOG equal DTW) |
Equal awareness concerning berth availability (NABSW) | (Administrative) Speed advancement and -delay effects are deemed not to apply for any route (i.e. absence of speed limitations concerning TSS) | |
Equal distance to FP when awareness of NABSW is gained | (Physical obstruction) Speed advancement and -delay effects are deemed not to apply for any route (i.e. absence of shallow water areas, narrow passages) | |
Common Due Dispatch (DD) Speed | Distance Increments of any nature (i.e. by island, off shore structures etc.) are deemed not to apply for/ to any route | |
Potential main engine utilisation to i.e. respond immediately to hazardous situations while adrift or at anchor is not taken into consideration | Â | |
Utilisation of distillate fuels for the operation of auxiliary engines is not taken into consideration | Â | |
Minimum safe and sensible navigation speed is deemed to be 9.0 nm/h | Â | |
FCFS mechanism | Continuous Due Dispatch (DD) Navigation | Â |
Static VAS mechanism | Notified Time of Arrival (term adapted from NVAS), 7 days | Â |
Prior to Notified Time of Arrival continuous DD speed applied | Â | |
FRL VAS | 1st. Vessel’s RTA deemed to be equal to the NABSW (JIT arrival) |  |
