Something like
Seafarer A - visa 1 xxx, visa 2 xxx, visa 3 xxx
Seafarer B - visa A xxx, visa 2 xxx

String Aggregate can be used to aggreagate multiple values to a single column
Please refer answer : List Aggreggate in SQL Server
For
Field A | Field B
1 | A
1 | B
2 | A
query
select FieldA, string_agg(FieldB, '') as data
from yourtable
group by FieldA
will give result
1 | AB
2 | A
For versions less than 2017 use
select distinct
SUBSTRING (
stuff(( select distinct ',' + [FieldB] from tablename order by 1 FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)')
,1,0,'' )
,2,9999)
from
tablename
