Lifting operation is not easy in the offshore environment, as complexity comes mainly from harsh weather conditions and inaccessibility:
- Limited available equipment: not feasible to rent additional equipment sailing in the middle of the sea
- Gravity center variation: not easy to guarantee a stable alignment on a vessel with strong wind or rough sea, disbalancing the cargo with pendulum effect
- Heavy-duty operations: the largest and heaviest cargos are moved off the shore for unlimited space (no bridges, no tunnels, no mountains)
- Harsh environment: unstable weather conditions, such as electric storms and strong wind
- Limited space for employees: handling and working space typically the same on a ship deck
Under these circumstances, safety goes first and crane hook is considered a top priority, as the whole cargo is lifted by this unique component.
Traditionally large crane hooks over 500 t have been considered casted and dynamic safety factors are lower than a forged hook. But it´s not easy to forge a massive hook over >3000 t.
For this reason, replacing old non-forged 4-prong hooks with 2 forged ramshorn ones is considered a SMART solution:
S: SAFETY & STRENGTH
M: MANUFACTURER
A: ADVANCED & ACCURATE
R: RELIABLE & RISKLESS
T: TRUST AND THINKING IN LONG TERM
