A CTV out and home in a day and an SOV living aboard for weeks are not the same clinical exposure. Advisory clinical support, sized to the fleet — a complement to your TMAS coverage, not a replacement for it.
Crewing and HSE plans are usually written per vessel class already. Medical cover rarely is — most retainers are priced as if every hull carries the same exposure.
Crew and accommodation figures are indicative ranges typical for vessels in these classes, not a claim about any specific operator's fleet.
Day rates in this class run roughly £2,000/day for a CTV, £30,000/day for an SOV, and $225,000–300,000/day for a WTIV. An avoidable early return costs the day rate on top of the case.

The TMAS obligation sits with you as the operator, not with any vendor you choose to complement it. Here is what the Swedish rule actually says, in its own words.
TSFS 2021:80, ch. 2 §§ 6–7: vessels on international voyages longer than three days with 100 or more crew must carry a doctor onboard.
TSFS 2021:80, ch. 2 §§ 6–7: every other vessel must carry at least one medical officer, with a duty to consult TMAS. That is the rule that actually lands on a CTV or an SOV on international voyages — the crew threshold for a doctor is rarely the binding one.
TSFS 2021:80, ch. 1 § 3: the regulation doesn't apply to vessels in domestic traffic operating in trading areas C–E, so a CTV in purely coastal domestic service falls outside it. MLC 2006 regulation 4.1 is widely cited as setting a broadly similar international threshold. Exactly how any of this applies to an SOV standing still at a wind park for weeks is a genuinely open question, decided by flag state and your own risk assessment — not something we resolve on this page.
The medical record stays onboard and belongs to the vessel, not the responder (TSFS 2021:80, ch. 6 §§ 2–4 — a 10-year retention duty). There's no longitudinal relationship across a crew member's cases.
“In port, the medical officer may only use Tele Medical Assistance Service when the help required cannot be obtained by other means” (TSFS 2021:80, ch. 2 § 4, verbatim).
There's no mechanism to aggregate case data into your systematic work-environment reporting.
No mental health track, no chronic-condition management, no fitness-for-duty assessment between cases.
Not a substitute for MRCC / emergency coordination, and not a claim that Alvyri Crew is a TMAS provider — Swedish TMAS is a state service, clinically delivered by Kry since 6 November 2024.
CTV and SOV crews are seafarers under STCW and MLC, not wind technicians under GWO. Swedish medical-officer training under STCW 2010 is certified by the Swedish Transport Agency (Transportstyrelsen) — a five-day base course with a four-day refresher every five years.
That's a shorter, more direct path for a maritime crew than the GWO route we already run for onshore wind technicians — it complements it rather than replacing it. GWO stays exactly what it is on the offshore wind side: aligned to GWO standards, not a GWO accreditation. The exact requirements to become an approved STCW training provider are still being scoped on our side, and we're not claiming that status today.
