Net profit stood at $25.3m, $2m more than the corresponding period of 2013.
Revenue climbed from $96.7m last year to $145m.
Siem’s main divisions – platform supply vessels (PSVs), offshore subsea construction vessels (OSCVs) and anchor handling tug supply vessels (AHTSs) – contributed equally to revenue.
Siem recorded high utilisation of its fleet with more than 90% of its vessels under contract.
The Oslo-listed company expects the spot market for the fourth quarter to be volatile for AHTSs, while it guides for a soft winter period for PSVs.
